This was an early piece, with the URL in the text. We have since moved it to the footer, a la The Best of MAKE.
There are no limits to page lengths, although long, complicated projects, with lots of steps and photos have been kept to a minimum.

Definitely. We *do* have some long projects in the book. As with The Best of MAKE, we tried to strike a balance of projects, from ones you can do in a few minutes to ones you might spend a weekend on. We didn't want to do too many long-form projects because they take up so much real estate that might accommodate a number of smaller projects. We spend a lot of time futzing with this mix, trying to get it right.

It's also been a learning process figuring out how to go from web how-tos (where you can have lots of images, video, slideshows to get your idea across) to print how-tos, where space is at a premium.
